Struct EarlyContextAndPass 

pub struct EarlyContextAndPass<'ecx, 'tcx, T: EarlyLintPass> {
    context: EarlyContext<'ecx>,
    tcx: Option<TyCtxt<'tcx>>,
    pass: T,
}

Implements the AST traversal for early lint passes. T provides the check_* methods.

Fields

context: EarlyContext<'ecx>

tcx: Option<TyCtxt<'tcx>>

pass: T

Implementations

impl<'ecx, 'tcx, T: EarlyLintPass> EarlyContextAndPass<'ecx, 'tcx, T>

fn check_id(&mut self, id: NodeId)

fn with_lint_attrs<F>( &mut self, id: NodeId, attrs: &[Attribute], f: F, target_span: Span, )

where F: FnOnce(&mut Self),

Merge the lints specified by any lint attributes into the current lint context, call the provided function, then reset the lints in effect to their previous state.

Layout

Note: Unable to compute type layout, possibly due to this type having generic parameters. Layout can only be computed for concrete, fully-instantiated types.
